[How To AI @HowToAI_]

MIT's Nobel Prize-winning economist proved that AI is mathematically guaranteed to destroy human knowledge.

They published a massive NBER paper modeling the long-term impact of AI on human cognition.

And they found the most alarming conclusion in the AI literature so far.

It’s called "Knowledge Collapse."

Here is how human progress actually works.

When you struggle to solve a complex problem, you generate two things:

General knowledge about how the world works, and context-specific knowledge about your exact problem.

Normally, humans acquire both at the same time. You do the hard work to solve your specific problem, and in the process, you learn a general principle.

You share that principle. That is how human knowledge grows.

Then comes Agentic AI.

AI is incredibly good at giving you the exact, context-specific answer you need right now. It hands the solution to you on a silver platter.

So you stop doing the hard work.

And because you stop doing the work, you stop generating the "general knowledge" that society relies on.

Acemoglu calls it the "knowledge-collapse equilibrium."

When AI reaches a certain accuracy threshold, the incentive for humans to learn drops to zero.

Nobody verifies. Nobody explores. Nobody discovers new fundamental truths.

Society gets increasingly sophisticated automated outputs, while our actual capacity to generate new knowledge quietly erodes.

But here is the most terrifying finding in the paper.

Welfare is "non-monotone" to AI accuracy.

That means as AI gets more accurate, society actually gets worse off.

Denmark’s PM Mette Frederiksen:

There is a total established link between power, political power, capital, tech giants and AI. And the purpose of this is undermining democracy.

That's the goal because the people who are developing this stuff are against democracy.

I met Sam Altman a couple of years ago. I spent hours with him and at the end of the discussion I said to him, "You have created a monster."

And he said, "Yes, and now it's up to you to find out how to deal with it."

Generative AI doesn’t run on magic. It runs on massive data pipelines built on privacy violations by design.

Our new @Amnesty report exposes how big tech’s AI systems are powered by surveillance, data extraction, and abuse of people’s rights, at scale.

We researched the models powering some of the most popular publicly available standalone generative AI tools, including GPT 3 by Open AI, Google’s Gemini, Meta’s Llama, DeepSeek and tools by Midjourney and Stable Diffusion.

This is not innovation at any cost. It comes at a high price: our human rights.

[AI Highlight @AIHighlight]

🚨BREAKING: Anthropic just published a study mapping exactly which jobs its own AI is replacing right now.

The workers most at risk are not who anyone expected. They are older. They are more educated. They earn 47% more than average. And they are nearly four times more likely to hold a graduate degree than the workers AI is not touching.

The argument is straightforward. Anthropic built a new metric called "observed exposure." Not what AI could theoretically do. What it is actually doing right now in professional settings, measured against millions of real Claude conversations from enterprise users.

For computer and math workers, AI is theoretically capable of handling 94% of their tasks. It is currently handling 33% of them. For office and administrative roles, theoretical capability is 90%. Current observed usage is 40%. The gap between what AI can do and what it is already doing is enormous. The researchers are explicit about what comes next. As capabilities improve and adoption deepens, the red area grows to fill the blue.

The demographic finding is what makes the paper uncomfortable. The most AI-exposed workers earn 47% more on average than the least exposed group. They are more likely to be female. They are more likely to be college educated. This is not a story about warehouse workers or truck drivers. It is a story about lawyers, financial analysts, market researchers, and software developers. The exact group whose education was supposed to insulate them.

Computer programmers showed the highest observed AI exposure at 74.5%. Customer service representatives at 70.1%. Data entry keyers at 67.1%. Medical record specialists at 66.7%. Market research analysts and marketing specialists at 64.8%. These are not predictions. These are measurements of work that is already happening on AI platforms right now.
Then there is the pipeline finding nobody is talking about loudly enough.

Anthropic's researchers found a 14% decline in the job-finding rate for workers aged 22 to 25 in highly exposed occupations since ChatGPT launched. No comparable effect for workers over 25. Entry-level roles were never just jobs. They were the training ground where junior analysts became senior analysts, where junior lawyers learned how arguments hold together. If that layer disappears, nobody has answered the question of where the next generation of senior professionals comes from.

The detail buried in the paper that most coverage missed: 30% of American workers have zero AI exposure at all. Cooks. Mechanics. Bartenders. Dishwashers. The technology reshaping professional careers is completely irrelevant to roughly a third of the workforce. The divide is no longer between high skill and low skill. It is between presence and absence.
The company publishing this study is the same company selling the AI doing the replacing. Anthropic had every commercial incentive to soften these findings. They published them anyway.

If you spent four years and $200,000 on a degree to land a white collar career, the company that builds Claude just confirmed your job is more exposed than the bartender pouring drinks at your graduation party.

🇫🇷 FRANCE JUST FIRED MICROSOFT.

2.5 million government devices. Off Windows. Onto Linux.

This isn't a pilot. Every ministry has been ordered to submit a migration plan by autumn 2026. The OS, cloud infrastructure, AI platforms, collaboration tools. All of it.

The minister's words: "We can no longer accept that our data, our infrastructure, and our strategic decisions depend on solutions whose rules, pricing, and risks we do not control."

They already replaced Teams and Zoom with a homegrown video tool. Health data is moving off American cloud by end of year.

And this isn't even new ground for France. Their national police force already moved 100,000 devices to a custom Linux build. Saves €2M a year in licensing.

If this works, every EU government is watching.

Microsoft has not commented.

NEWS: Massive budget cuts for US science proposed again by Trump administration

"It's an extinction-level event for science".

The US government is proposing massive cuts to almost every branch of science, from NASA to the National Institutes of Health. NSF would completely eliminate the social, economic and behavioral sciences directorate.

This would decimate the world's leading scientific system.

Comme on le dit dans nos paroles depuis 40 ans, lorsqu’on était des adolescents, on pensait que la violence, la force brute faisait trembler le système. Depuis dimanche dernier au vu des réactions racistes et défiantes face à l’élection du maire de Saint-Denis, j’ai la confirmation que ce qui terrorise ce système c’est que les gens des quartiers populaires aillent tous voter. Pire, qu’ils raflent des mandats et qu’ils participent à la vie politique au lieu de quémander en attendant la réalisation illusoire de milles promesses, y compris celles faites par une gauche méprisante et paternaliste. Au final, beaucoup de personnes issues des milieux modestes aiment plus la France que tous ces comédiens réunis. Une inscription massive sur les listes électorales les fera toutes et tous trembler parce que la perte de leurs petits privilèges c’est l’épouvantail de la fin.

[Camille Adam (Au nom de l'Europe) @aunom2leurope]

Je lance aujourd’hui une bouteille à la mer sur ce réseau. Cela fait 4 mois que mon documentaire « Au nom de l’Europe » est sorti et bien que son nombre de vues soit assez honorable pour sa durée et la nouveauté de la chaine, je ne peux cacher ma déception. Le film, fruit de trois années d'enquête et de documentation, est disponible gratuitement et a été intégralement financé par mes économies personnelles.

Seuls @montebourg, @SouveraineTech et @RaveaudGilles et quelques autres membres de de réseau ont relayé le film et pour cela je leur suis reconnaissant infiniment.

Pourtant, l’actualité ne cesse de rappeler à quelle point la question européenne écrase nos existences et notre destin : endettement de la France, crise budgétaire, procédure de déficit excessif, affaire du Doliprane vendu aux américains, ratification de l’accord Mercosur, nombre de faillites record, réforme perpétuelle de l’assurance-chômage, hausse des prix de l’électricité. Tout cela quasiment en près d’un mois, ce ne sont pas les exemples qui manquent.

Le film appuyé par un grand nombre d’archives et d’interviews, notamment d’anciens ministres français et allemand, retrace les 40 dernières années de construction européenne et les démantèlements successifs des outils de souveraineté de la France face au marché qui s’en sont suivis.

Le film revient sur la guerre menée par la Commission européenne contre nos services publics, la libéralisation des mouvements de capitaux ayant permis le rachat de nos fleurons nationaux , la généralisation des accords de libre-échange, le rôle de l’euro dans la désindustrialisation…autant d’évènements où la France, ou plutôt ses dirigeants, n’a pas été que victime mais le plus souvent actrice de son propre asservissement.

Je ne suis évidemment pas objectif en disant cela mais je pense pourtant que ce documentaire a le potentiel de vulgariser considérablement le débat sur la question européenne pour nombre de nos concitoyens, et ce, loin des mythes et des slogans. Rien que des faits pour un débat sérieux, pour un consentement libre et éclairé sur ce que nous sommes prêts à accepter au nom de l’Europe.

J’en appelle aux personnes présentes sur ce réseau et attachés à la justice sociale à m’aider à relayer ce travail d’éducation populaire.
